Yes, I would pot it up quickly in a tiny seedling tube. Keep it lightly moist but not soaked.

The tiny ones on the mother plant I would remove them with a chunk of cane each. Do the same with these as you did with the other keiki. I have managed to grow plants on like this.

I would unpot the mother plant and try to save the new shoot, if you leave it with the dying plant it could well die too.

i added it to a pot with my generic pink Phalaenopsis that has moss that stays moist for two weeks at a time. I put it under about 1/10 inch of moss where it can get air but not dry, is that ok?

That should be ok Tosh, I often put keiki into the side of other plants when I'm walking around my orchids outside. If it's not going to survive you will see it start turning brown.

Hope it does ok.:)

well, after a long time of living, the last keiki just died today...
It was close!

Sorry to hear that Tosh :(

Keiki on dend. dying
 

Tosh, I was following your post. How did that little keiki go, did it survive? I too had little keikis that I wrapped in spagnum moss and put into a tiny pot, 2 inches and suspended it from the roof of the greenhouse, and lo and behold in 2 weeks, roots everywhere. Then I potted it in light bark and pearlite, and is as healthy as ever. Good luck.:waving

Sorry Tosh, I only new to this, but I didn't read the next page, where you advised your last keiki died. I'm so sorry.
